Brood V

from Wikipedia, the free encyclopedia

Brood V ( Brood 5 ) is a population of the "Periodic Cicadas" ( Magicicada ) in the northeastern United States . Every 17th year, Brood V en masse cicadas burrow to the surface, lay eggs and die within a few weeks.

At the beginning of the 20th century, the entomologist Charles Lester Marlatt identified 30 different populations, of which around 15 could also be confirmed over the years. Brood V is one of the 12 populations with a life cycle of 17 years.

Brood V last performed in spring 1999 and spring 2016, and is expected to recur in 2033 Template: future / in 5 yearsand 2050 Template: future / in 5 years. The population is distributed across Ohio , southwest Pennsylvania , northern parts of West Virginia (excluding the Eastern Panhandle ), western Maryland , and some areas of Virginia . Additionally there is an isolated population in Suffolk County , Long Island , New York .

The 4 cm long (1.5 in) black insects cannot sting or bite. As soon as they reach the surface of the earth, they molt, leaving the empty larval skins on the ground. They climb trees and bushes, mate and die after about two weeks. Up to one million specimens per hectare (2.5 acres) can occur.
